Embodiment Construction
[0044] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0045] figure 1 A filter device 100 for filtering formaldehyde includes: a first filter layer 10 , a second filter layer 20 , a third filter layer 30 and an installation frame 40 . The installation frame 40 is used for installing the first filter layer 10 , the second filter layer 20 , the third filter layer 30 and the installation frame 40 , the installation frame 40 is rectangular, and an installation opening 41 is formed in the middle of the rectangular installation frame 40 . The first filter layer 10, the second filter layer 20 and the third filter layer 30 are all folded structures. The first filter layer 10 , the second filter layer 20 and the third filter layer 30 are sequentially stacked and disposed in the installation opening 41 of the installation frame 40 . Wherein, the first filter layer 10 is fixedly installed on the inst...

The invention discloses a filter device for filtering formaldehyde. The filter device comprises a first filtering layer, a second filtering layer, a third filtering layer and a mounting frame, a mounting opening is formed in the mounting frame, the first filtering layer, the second filtering layer and the third filtering layer are of folding structures, the first filtering layer, the second filtering layer and the third filtering layer are sequentially arranged at the mounting opening of the mounting frame in a mutual overlapping manner, the first filtering layer is fixedly mounted on the mounting frame, the second filter layer and the third filter layer are detachably connected to the mounting frame, and a plurality of vent holes are formed in a folding part of the second filter layer. According to the filtering device for filtering the formaldehyde, the vent holes for increasing the ventilation quantity are formed in the folding part of the second filtering layer, so that the problemof overlarge wind resistance caused by overlarge density of the multi-layer overlapped filtering layer at the folding position can be solved. The overall area of the second filter layer is reduced through the vent holes formed in the folded parts, and the effects of adjusting the flow of the filter layer and prolonging the reaction time are achieved.
Description
technical field [0001] The invention relates to a filter device for filtering formaldehyde. Background technique [0002] The existing filter structure for removing formaldehyde is generally formed by stacking multiple layers of filter screens in series after being folded. After the multi-layer filter is folded and stacked, there is a significant difference in the density of the folded part and the non-folded part. Specifically, the space density of the folded portion is higher, so the wind resistance of the folded portion is large, and the air flow in the folded portion is not smooth, resulting in adverse consequences such as blockage. Contents of the invention [0003] The invention provides a filter device for filtering formaldehyde, which adopts the following technical scheme: [0004] A filter device for filtering formaldehyde, comprising: a first filter layer, a second filter layer, a third filter layer and an installation frame; [0005] The installation frame is...
